When displaying a square-type image with peak luminance for approximately 500 h in a 42 in. plasma display panel TV with high Xe (15%) content, halo-type boundary image sticking was observed in the nondischarge region adjacent to the discharge region. The halo-type boundary image sticking phenomenon is due mainly to the redeposit of the Mg species on the MgO layer in the nondischarge region adjacent to the discharge region, which is verified by measuring the redeposited Mg species in the boundary image sticking region using a cross-sectional scanning electron microscope. Based on this result, three kinds of solution to remove the boundary image sticking of an ac plasma display panel are introduced. First, we completely recover the boundary image sticking cells by using a full-white aging process. Second, we prohibit the inherent production of boundary image sticking by sealing the plasma display panel under vacuum. The final solution is to prohibit the inherent production of boundary image sticking by use of lower gas pressure.
在具有高氙（15%）含量的42英寸等离子体显示面板电视中，当显示具有约500小时峰值亮度的方形图像时，在与放电区域相邻的非放电区域观察到晕圈型边界图像残留。晕圈型边界图像残留现象主要是由于镁物质在与放电区域相邻的非放电区域的氧化镁层上再沉积所致，这通过使用横截面扫描电子显微镜测量边界图像残留区域中的再沉积镁物质得到了验证。基于这一结果，介绍了三种消除交流等离子体显示面板边界图像残留的解决方案。首先，我们通过全白老化过程完全恢复边界图像残留的单元。其次，我们通过在真空中密封等离子体显示面板来禁止边界图像残留的固有产生。最后的解决方案是通过使用较低的气压来禁止边界图像残留的固有产生。
